Hey, guys. Sorry for the delay in answering. Been at GenCon.
Okay, don't quote me on this, because I'm not 100% certain, and I don't want anyone claiming I promised something we don't deliver. But I
think there's a map of at least one of the major city-states.
Perhaps one good question might be how some of the standard D&D races and creatures were adapted to the Hamunaptra setting? What went into some of the various decisions made in the setting? How compatable is Hamunaptra with other Green Ronin products, and non-Green Ronin products?
Without going into details that I can't divulge yet...
We gave some serious thought to each race, whether or not it had a place in the setting, and what that place was. (This applies not just to the PHB races, but other standard humanoids as well.) A few don't appear. Some have a larger part than they do in the default. And every one of them is changed in some form or fashion. They are changed culturally, historically, and in terms of religion. The elves of standard fantasy don't fit in an Egyptian culture. That doesn't mean we dont' have elves; it just means they have been rethought to feel Egyptian in both concept and form, yet still remain recognizably elves.
Or at least, that was certainly our intent. I believe we succeeded, but of course, you have no reason to think I'm impartial.

And I know I'm speaking in vagueries, not specifics, but as I said, I'm really not allowed to go into detail.
I
can say that CAS ran several demos at GenCon, and everyone who participated was quite happy with the results.
As for compatability...
Hamunaptra could easily be made into an exotic location in a standard D&D campaign, just as (to keep using the same examples) Nyambe or Rokugan could. While we've tweaked a lot, we've kept everything at more or less the same balance. I personally feel that Hamunaptra is strongest when used as a setting unto itself, but if you decide to drop a Western party into Hamunaptra, or vice-versa, you should have little trouble making it work.
I also have to correct something I said earlier. The set is being released in October, not September. Disappointing to have to wait a few more weeks, I know, but I honestly believe it's worth the wait.
